Trijicon ACOG 4×32
Video | What’s Included | Specs | Top Mounts | Pictures | Restrictions
An iconic magnified optic that’s still one of our favorites. Rugged, reliable, and one of the best in its class, the Trijicon ACOG 4×32 is as relevant as ever.
The Trijicon ACOG is a fixed-power compact riflescope with an illuminated chevron reticle. It is designed to be extremely durable and reliable. Combining traditional, precise distance marksmanship with CQB speed, this variant includes a bullet-drop compensated (BDC) reticle. Every feature of its design was chosen for a single purpose: to provide increased hit potential in all lighting conditions. This is the TA31F, a 4×32 power scope designed for .223 rifles. It features dual illumination, with fiber optics for daylight illumination and tritium for illumination at night, and it’s waterproof to 100 meters. The glass is super clear, the reticle is easy to use, and the scope can easily be used to hit targets at 500+ yards.
